"The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others…"  -John Stuart Mill

"All within the state, nothing outside the state..."  -Benito Mussolini

"In the old days, we used to celebrate if somebody had a baby, we used to chip in and help him out with the hospital bills, if he happened to be hard-pressed for the moment. Now, if a baby was born, we didn't speak to the parents for weeks. Babies, to us, had become what locusts were to farmers."  -Ayn Rand
